Abstract
Description
Изобретение касается производства строительных материалов.The invention relates to the production of building materials.
Известна масса для производства плит, включающая, мас.ч.: воду 700; макулатуру 15; двуводный гипс или фосфогипс 85; мочевиноформальдегидная смолу 5; крахмал 2,5 [1].Known mass for the production of plates, including, parts by weight: water 700; waste paper 15; gypsum gypsum or phosphogypsum 85; urea-formaldehyde resin 5; starch 2.5 [1].
Задача изобретения состоит в сокращении расхода вяжущего в массе для производства теплоизоляционных плит при обеспечении их прочности.The objective of the invention is to reduce the consumption of binder in the mass for the production of heat-insulating boards while ensuring their strength.
Технический результат достигается тем, что масса для производства теплоизоляционных плит, включающая воду, макулатуру, фосфогипс, мочевиноформальдегидную смолу, крахмал, дополнительно содержит карбоксиметилцеллюлозу, причем компоненты находятся при следующем соотношении, мас.ч.: вода 340-360; макулатура 260-300; фосфогипс 40-60; мочевиноформальдегидная смола 4-6; крахмал 4-6; карбоксиметилцеллюлоза 4-6.The technical result is achieved in that the mass for the production of heat-insulating boards, including water, waste paper, phosphogypsum, urea-formaldehyde resin, starch, additionally contains carboxymethyl cellulose, and the components are in the following ratio, parts by weight: water 340-360; waste paper 260-300; phosphogypsum 40-60; urea-formaldehyde resin 4-6; starch 4-6; carboxymethyl cellulose 4-6.
В таблице приведены составы массы для производства теплоизоляционных плит.The table shows the composition of the mass for the production of insulating boards.
В процессе приготовления массы дня производства плит используют гидропушитель, в который подают воду (с избытком) и макулатуру, предварительно нарезанную на куски площадью 2-16 см2.In the process of preparing the mass of the day of production of the plates, a water extinguisher is used, into which water (in excess) and waste paper, previously cut into pieces with an area of 2-16 cm 2 , are supplied.
После распушивания макулатуры из образовавшейся массы удаляют излишнее количество воды, перекачивают ее в емкость, где массу перемешивают в течение 10-15 мин с карбоксиметилцеллюлозой, мочевиноформальдегидной смолой, крахмалом. Затем добавляют фосфогипс и осуществляют перемешивание еще в течение 1-3 мин. Из приготовленной массы формуют плиты, которые сушат до влажности не более 5%.After fluffing up the waste paper, excess water is removed from the resulting mass, it is pumped into a container where the mass is mixed for 10-15 minutes with carboxymethyl cellulose, urea-formaldehyde resin, and starch. Then phosphogypsum is added and mixing is carried out for another 1-3 minutes. Plates are formed from the prepared mass, which are dried to a moisture content of not more than 5%.
